Anplication filed July 17,1905- Serial No. 270,066.

To all whmvt it may concern:

Be it known that I, WILLIAM R. FOX, 9. citizen of the United States, residing at the city of Grand Rapids, county of Kent, State of Michigan, have invented certain ,new and useful Improvements in Stop Devices for "Type-Writers, of which the following is a specification.

This invention relates to improvements in stops for the carriages of type-writing inachines, and is more particularly adapted for use as a stop in connection with tabulating devices for type-writing machines.

The object of this invention is to 1provide an improved detachable adjustab e stop which is simple and easy to construct, whic is compact, occupying very little space along the stop-bar, and which can be very readily attached and detached and is very secure when in position.

Further objects relating to structural details will more definite] appear from the de tailed descri tion to follow I accomp ish the objects of my invention by the devices and means described in the following specification. I

The invention is clearly defined, and pointed out in the claims.

A structure embodying the features of my invention is clearly illustrated in the accompanying drawings, forming a part of this specification, in which Figure 1 is an enlarged rear elevation view of one ofmy improved stops in place on the stopbar of a tabulating device of a typewriter. Fig. 2 is an enlarged sectional side View taken on line 2 2 of Figs. 1 and 4. Fig. 3 is an enlarged sectional end view taken on line 3 3 of Fig. 2. Fig. 4 is an enlarged bottom view of my im roved stop in connection with a portion of t e stop-bar. Fig. 5 is an enlarged top view of my improved stop with a portion removed. N v

In the drawings, all of the sectional views are taken looking in the direction of the little arrows at the ends of the section-lines, and

slmilar letters of reference refer to similar parts throughout the several views.

Referring to the drawings, A represents'a part of the stop-bar of a tabulat-or for a typewriting machine, provided with a series of teeth A, forming a series of intermediate notches A. On this stop-bar A is mounted one of my improved stops, as shown in sectional detail in Figs. 2 and 3.

The body B of my improved stop is proved adjustable stamped or otherwise shaped from sheet metal of the same thickness as the width of one of the notches A. The sides of the body B of said stop are slotted transversely, as shown in Fig. 4, the width of said slot corresponding to the thickness of the solid portion of said stop-bar A that is, it corresponds to the body part of the bar not including the teeth. The said sides of the body B of said stop are parallel to .each other, so that the said body may be readily and easily applied, the parts I) I) being received in the notches A of the stop-bar A, thus firmly, ei'liciently, and detachably holding the said stop in position, so that the type-writer carriage can be arrested at any desired point. A portion of the body B is bent upward, so as to form the finger-piece B. One of the parts I) is cut away, so that only a single thickness of metal is presented asa cnntactwith the carriage.

The lever C, which is also preferably stamped out from sheet metal, consists of the finger-piece C, necks, and catch C. The lever (J is passed down sidewise through a slot 0 in the top of the body B and is then turned so that the lever C will be held in place by the shoulders on each side of theneck When the stop is slipped over the stop-bar A, the catch 0 will engage the lower side of the said stop-bar and is held normally in place by the spring D, which is suitably secured to the top of the body B by a screw D. Any suitab e'means, however, may be used for securingsaid spring D to the frame B. I

have illustrated and described my imand detachable stop in the form preferred by me on account of its simple and economical construction. I am aware that the structural details may be considerably varied without, however, departing om my invention. Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is v 1. In a stop device, the combination of a notched stop-barya U-shaped body having anupwardly-projecting finger, formed from sheet metal, the sides of which are slotted so that the body may embrace the notched stop-. bar and the edges of the slots engag I the notches of said stop-bar; a lever, provided with a catch, passing down through a slot in said body, the said catch engaging the lower edge of'said stop-bar; and a s ring secured to the top of said body, for ho ding said lever normally in position, for the purpose specified.
